Medium is an interesting blogging tool. Sometimes I love the UI and sometimes I find it frustrating.

I settled for pasting it in from another site.
I don’t think I’ll continue doing it for any personal blogging. I want to own my own long form content and I think it’s important to keep your work in a place that won’t get shut down on a whim when the VC money runs out or if the parent company closes the door.
